Shares of Michael Kors (Nasdaq: KORS) hit a 52-week high last week. Let's take a look at how it got here to find out whether there are still clear skies ahead.

How it got here
There are significant variations in performance across the fashion sector, even in the luxury subsector that Michael Kors might be said to inhabit. But there's clearly no competition for Kors to date. The stock has been on an absolute tear since going public late last year, and has left even high-flying, cultish yoga-pant purveyor lululemon athletica (Nasdaq: LULU) in the dust:

Kors' recent surge came after a strong quarterly performance blew out expectations, but the company's been a fast grower for some time, and its stock price reflects that fact. Just take a look at some of Kors' numbers compared to its peers.

What you need to know
Kors sports a premium price even in a sector well-known for its premium pricing. There's one reason for that, as you can see:

Company

P/E Ratio

Price to Free Cash Flow

Net Margin (TTM)

3-Year Annualized Income Growth

Michael Kors 57.5 331.3 11.9% 78.7%
Lululemon 46.5 61.7 17.9% 50.3%
Coach (NYSE: COH) 17.2 16.9 21.3% 12.3%
Fossil (Nasdaq: FOSL) 18.6 32.0 11.2% 29.7%
Estee Lauder (NYSE: EL) 29.0 34.1 8.8% 21.5%

The market seems to expect continued strength out of Kors, but it'll have to fly like a rocket to justify its currently exorbitant P/E and even more outlandish P/FCF. The company's net margin is nothing to write home about when compared to Lululemon or Coach, and Fossil and Estee Lauder both offer cautionary examples of what its ratios may dwindle to if income growth slows.

It's especially important to look at Fossil when considering Kors' market future. My fellow Fool Sean Williams highlighted Fossil's recent 52-week low, which came after a tremendous two-year run ended with a splat this summer. That seemed like a major overreaction, and the company isn't expecting to start losing ground anytime soon, but that doesn't help anyone who got in before the plunge. One sniff of blood in the water, even if it's just a scratch, and the sharks will probably be all over Kors just as they've been on Fossil.

What's next?
Where does Michael Kors go from here? How strong will its sales growth be this quarter, and the quarter after that? As long as there's fuel in the rocket, this stock will keep soaring. Unfortunately, few people really know when that rocket's going to run out.

The Motley Fool's CAPS community has given Michael Kors a two-star rating, with 80% of the CAPS players who weighed in expecting the company to keep beating the market.
